SHOCK-LOADING MACHINE.

SPECIFICATION forming part of Letters Patent No. 405,840, dated June 25, 1889.

Application filed February 4, 1889. Serial No. 298,662. (No model.)

To all whom it may concern.-

l Be it known that I, WILLIAM J. JAcoBs, a citizen of the United States,residing at Bargersville, in the county of Johnson and State of Indiana,have invented a new and useful Improvement in Shock-Loading Machines, ofwhich the following is a specification.

My invention relates to an improvement in that class of machines forloading shocks of hay, corn-fodder, or like crops, upon a wagonbed,which consists of a lever mounted upon a vertical standard, so as toswing vertically and horizontally thereon, said vertical standard beingerected on the wagon-bed.

The objects of my improvement are, first, to provide greatlifting-power; second, t0 provide improved means for engaging anddisengaging the shock, and, third, to provide means for easilydismounting the vertical standard and the parts carried thereon, all ashereinafter fully described.

Figure l represents a plan of the loading device in position on thewagon-bed or hayrack; Fig. 3, a side elevation of the same; Fig. 3, apartial elevation, showing on a larger scale the Inechanism for engagingand disengaging the shock. Fig. 4 is a perspective view of the base andthe mast separated.

The base of the loader consists of two beams A and B, framed together toform a Tshaped frame, and a tubular sleeve C, supported above the pointof intersection of beamsA and B by braces d d and e. This base ispermanently secured to the wagon-bed D by bolts passing' through theframe, or in any other suitable manner.

F is a short cylindrical mast adapted to tit into sleeve C so as to turneasily therein. The lower end of the mast is provided with a pin h,which enters a corresponding hole /L' in the base. A lever J is pivotedat one end by a pin k to the mast, above and near the sleeve C. A secondlever K is hinged to a fulcrum f, which enters a socket in the top ofthe mast, and its shorter arm is connected with lever J by a chain l. Acompound lever is thus formed, which swings in a vertical plane on themast and swings in a horizontal plane by turning the mast in sleeve C.The free P is a flat metallic bar having at one end L* an eye q toreceive the rope n, and having the other end bent to one side andprovided with a stud o'.

S is a thin flat disk having a central hole, and having in its edge adeep notch t and a smaller notch u, the arrangement being such that whenthe disk is mounted on stud r, so

as to turn loosely thereon, and notch t is,

turned upward, bar P and stud r will stand between the notches. The diskis temporarily held in the above-described position by means of a pawlc, pivoted to bar P, and ar ranged to engage notch 'a in the disk. Alight cord w is attached to pawl fn and is passed through an eye a; onthe lever K, and thence along levers K and J within convenient reach ofthe operator.

The operation of my device is as follows: The wagon-bed or hay-rackcarrying the device having been placed near the shock to be loaded, thefree end of lever K is swung outward and depressed until the trip-hook,depending therefrom, is within reach of an attendant. The attendantplaces the binder of the shock in notch tof disk S- and engages notch awith pawl c. The operator then, pulling downward on rope m, raises thefree end of lever K and the shock, at the same time turning the mast bymeans of lever J, and thus swinging the shock over the wagon-bed. Whenthe shock has been brought into position, the operator pulls cord w andthereby discharges pawl e from notch u in disk S. The weight of theshock now causesdisk S to turn on stud o' until the binder of the shockslips out of notch z., thus discharging the shock upon the wagon-bed.After the load has been obtained, or when the wagon is required forother purposes,the mast and the parts mounted IOO thereon may be quicklyremoved by liftingthe having notches t and u, the paWl pivoted to romast out of sleeve C. AThe base then takes the bar and arranged toengage one of said up but little space andrneed not bereinoved. notches,and the trip-oord attached to Said I claim as my inventionpawl, al1arranged to co-operate substantially 5 In a shock-loading machine, theoombinaas and for the purpose speeiied.
